Sec.  1500.5  Hazardous mixtures.

    For a mixture of substances, the determination of whether the 
mixture is a ``hazardous substance'' as defined by section 2(f) of the 
act (repeated in Sec.  1500.3(b)(4)) should be based on the physical, 
chemical, and pharmacological characteristics of the mixture. A mixture 
of substances may therefore be less hazardous or more hazardous than its 
components because of synergistic or antagonistic reactions. It may not 
be possible to reach a fully satisfactory decision concerning the toxic, 
irritant, corrosive, flammable, sensitizing, or pressure-generating 
properties of a substance from what is known about its components or 
ingredients. The mixture itself should be tested.
